LEVER-ARM FOR GUNS.

Specification of Letters Patent.

Patented Nov. 16, 1920.

Application filed June 4, 1920. Serial No. 386,430.

To all whom it may concern.

Be it known that I, CHARLES F. LnrEvnR, a citizen of the United Statesof America, residing at Plymouth, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements inLever-Arms for Guns, of which the following is a specification,reference being had therein to the accompanying drawings.

The invention relates to a construction of lever arms for guns and moreparticularly for spring air guns and it is the object of the inventionto obtain a construction formed of reinforced sheet metal, ashereinafter set forth.

In the drawings:

Figure 1 is a plan view of the sheet metal blank from which the leverarm is formed;

Fig. 2 is a longitudinal section through the blank after the forming andreinforcing of the same;

Fig. 3 is a perspective view of the lever iLTIHl slightly modified inconstruction from Figs. 4:, 5 and 6 are cross sections respectively onlines 44E, 55 and 6-6 of Fig. 2.

In the construction of spring air guns one type employs a lever forplacing the spring under compression when the gun is loaded. This leveris suitably fashioned to cooperate with the stock and frame of the gunand is usually formed of a malleable casting. With the present inventionI have substituted a sheet metal stamping for the casting, which is usedin cooperation with a rod reinforcement to form a lever of the desiredcontour.

In detail, A is a sheet metal blank which is bent into a U-shaped crosssection and is simultaneously otherwise fashioned to the form shown inFigs. 2 and 3. As shown in Fig. 4, a portion B of the blank is left ofthe of the U cross-section, so as to form an in- Wardly opening channelfor engagement with the cooperating parts of the mechanism. This portionalso is provided with the apertures C in the sides thereof for thepassage of a fulcrum pin. Beyond the por" tion B is a portion D, inwhich the blank is closed in to form a complete section and beyond theportion D is a portion E which is reinforced. This reinforcement isprefer ably formed of a round rod F, suitably fashioned and placed inengagement with the blank after the first U-ing operation, being securedby the bending in of the flanges, as shown in Fig. 6. IVith theconstruction shown in Fig. 2 the reinforcement F is return-bent at itsouter end and at its inner end is bent into an S-shaped form suitablefor engagement with the stock of the gun. In Fig. 3 the reinforcement isbent to form a complete loop, as indicated at F, but is secured in thesame manner.

At the points where the reinforcement passes out from engagement withthe sheet metal, the latter is enlarged to form rounded nipples G andthese serve to additionally strengthen the structure.

hat I claim as my invention is:

1. A lever for guns comprising a sheet metal blank pressed to form aportion of open U-shaped cross section, and a portion of closed hollowcross section, and a rod forming a reinforcement for said closedsection.

2. A lever for guns comprising a sheet metal blankhaving a portionformed into an open U-shaped cross section, and adjacent portions formedinto a hollow closed section, and a reinforcement formed of a rodfilling said closed hollow section and extending outward laterally ofthe lever.

3. A lever for guns comprising a sheet metal blank fashioned. to form aportion of open chanel or U-shaped cross section, a portion of closedhollow cross section, and a reinforcement formed of a rod for filling aportion of the closed hollow cross section, the end portions of said rodprejecting laterally, and rounded nipples formed on said blank forsurrounding the outwardly projecting portions of said rod.

In testimony whereof I affix my signature.

CHARLES F. LEFEVER.
